Reaction Steps

To a mixture of 6-(3-bromopropoxy)-3-methyl-1-benzofuran (87 mg, 0.32 mmol) (Example 63) and ethyl [(1S)-5-hydroxy-2,3-dihydro-1H-inden-1-yl]acetate (59 mg, 0.269 mmol) (Example 6) in DMF containing 1 vol % water (2.4 mL) was added Cs2CO3 (105 mg, 0.323 mmol). The mixture was stirred for 68 h at 80° C., and the reaction mixture cooled to rt, then concentrated under reduced pressure. The residue was suspended in EtOAc and filtered through a small plug of silica to give 119 mg (90%) of a light-yellow solid that was used in the next step without further purification.
